EDWIN M. FITZGERALD, OF N EW YORK, N. Y.

ADVERTISING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 251,855, dated January3, 1882.

Application filed May 27, 1881. (No model.)

To all whom it may concern Be it known that I, EDWIN FITZGERALD, of thecity, county, and State of New York, have invented a new and ImprovedAdvertising Apparatus, ofwhich the following is a specification.

Figure 1, Sheet 1, isa front elevation of my improvement, partly insection. Fig. 2, Sheet 1, is a sectional plan View of the same, takenthrough the line 2 z, Fig. 1. Fig. 3, Sheet 2, is a" sectional sideelevation of the same, taken through the line as at, Fig. 1. Fig. 4,Sheet 2,

is a sectional side elevation of the same, taken through the line y y,Fig. 1. Fig. 5, Sheet 2,

is a sectional elevation of a part of the operating mechanism.

Similar letters of reference indicate corresponding parts.

The object of this invention is to secure the automatic changing of aseries of advertisements at regular intervals.

The invention consists in an advertising apparatus formed by combiningwith a clockwork a series of rollers carrying an endless band, andasprin-g-driven chain of gear-wheels, a cam, a cam-operated lever, aweighted triplever, a set of catch-arms-and their shaft, a gear-wheelhaving a catch-pin, a sin gle-toothed ratchet-wheel, and a shaft,whereby the band will be moved automatically through fixed distances atregular intervals, as will be hereinafter fully described.

In the accom panyin g drawings, Arepresents the case or frame of theapparatus, to suitable supports in the upper part of which is attached aclock-work, B. The clock-work B is made in the ordinary manner, exceptthat one of the shafts is provided with a cam, G. I prefer to attach thecam O to a shaft revolving once a minute; but it can be attached to ashaft having a faster or a slower movement, as may be required. The.clock-work B is designed to be provided with a dial, D, a minute-hand,E, and an hour-hand, F, in the ordinary manner.

G is a lever, which is pivoted to the frame of the clock-work B, or someother suitable support, in such a position that the inner end of thesaid lever will be struck and operated by the cam O at each revolutionof the cam. The outer arm of the lever G passes beneath the outer arm ofa lever, H, which is pivoted to the frame I. The inner arm of the leverHisbent to one side in such a position that when the outer arm of thesaid lever H is raised the end of the inner arm will be moved inward, so

as to receive a pi J, attached to a wheel, K, pivoted to the frame I,and thus stop the movement of.the said wheel K. The outer end -of theleverH is made heavy, or has a weight, L, attached to it, so that thesaid outer end, when released by the descent of the outer arm of thelever G, will drop and withdraw the inner end of the said lever from thepin J, allowing the wheel'K to revolve. I

To the outer part of the frame I is pivoted a shaft, M, to which isrigidly attached an arm, N. The arm N projects upward, is bent inward,is then bent to one side, and its end passes across the upper side ofthe weighted arm of the lever H, so that the arm N will be raised byraising the said weighted arm of the lever H.

To one end of the shaft M isrigidl y attached an arm, 0, which projectsinward, and has its inner end bent down ward into hook form to engagewith the pin J of the wheel K, and thus stop the said wheel. To theother end of the shaft M is rigidly attached an arm, P, which projectsinward, and has a hook: formed upon its inner end to engage with thesingle-toothed ratchet-wheel Q, attached to the shaft It. The catch-armP is made heavy, so that whenthe trip-arm N is released by the descentof the weighted arm of the lever H the weight of the said catch-arm Pwill turn the shaft Maud lower the catch-arm 0 into position to engagewith the pin J of the wheel K and lower the said catch-arm P upon theratchet-wheel Q, ready to engage with the tooth of the saidratchetwheel. The shaft R is connected by a chain of gear-wheels, S,with the stopand trip-wheel K, and with a coiled spring, T, connectedwith the frame I. The shaft of the spring T is connected with it sgear-wheel by a pawl and ratchet in the ordinary manner, so that thesaid shaft can be turned to wind up the spring T without turning thegear-wheels S. .The shaft R revolves in hearings in the case or frame A,and is extended beneath the clock-work B.

To the extended part of the shaft R is attached aroller or drum, U,around which passes an endless apron or band, V. The band V also.

passes around five drums or rollers, W, more or less, as the desiredlength of the band V may IOC require. Upon the band V is designed to beprinted or otherwise formed a series of advertisements, which aredesigned to be exhibited, one at a time and successively, through aglass plate, X, secured in an opening in the lowerpart of the front ofthe case A.

With this construction, as the cam 0 comes. in contact with the lever Git raises the outer end of the said lever G and the weighted end of thelever H, bringing the inner end of the said lever H into position toreceive the pin J of the wheel K. The upward movement of the lever Hraises the catch-arms O and P out of gear and holds the said arms raiseduntil the spring '1. has turned the wheel K so far as to bring the pin Jin contact with the end of the lever H and has turned the shaft B so farthat the hook of the catch-arm P has been carried past the tooth of theratchet-wheel Q. As the lever G is released from the cam O the weightedend of the lever H withdraws the inner end of the said lever from thepin J and allows the wheel K and the shaft It to be revolved by thespring T, the end of the catcharm Priding upon the ratchet-wheel Q,ready to engage with the tooth of the said ratchetwheel Q when the shaftR has completed a revolution. The roller U, that drives the band V, isso arranged in size that one revolution of the shalt R and roller U willmove the hand V sufficiently far to carry one advertisement out of sightand bring the next one into View.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1 An advertising apparatusconstructedsubstantiall y as herein shownand described, consisting of theclock-work B, the series of rollers U W, carrying an endless band, V,the springdriven chain of gear-wheels S, the cam O, the lever G, theweighted catch-lever H, the arm N, the trip-arms O P and their shaft M,the gear-wheel K, having pin J, and the singletoothecl ratchet-wheel Q,as set forth.
